摘要： A media for perpendicular recording and a method of creating the media is provided. The media includes a hard recording layer and a soft underlayer (SUL). The SUL is composed of at least two anti-ferromagnetically coupled (AFC) sub-underlayers. The sub-underlayers respond to a magnetic field established during dynamic reversal with respective magnetic fields. The sub-underlayers are formed and disposed to differ in one or more magnetic moment, anisotropy, and thickness, so that their respective magnetic fields constructively interfere in one or more points in the hard recording layer, thereby reducing a total SUL magnetic field response to the dynamic reversal field approximately to zero at one or more points in the hard recording layer, which reduces side track erasure.
摘要翻译： 提供了用于垂直记录的介质和创建介质的方法。 介质包括硬记录层和软底层（SUL）。 SUL由至少两个反铁磁耦合（AFC）子底层组成。 副底层响应于用相应的磁场在动态反转期间建立的磁场。 亚底层被形成和设置为在一个或多个磁矩，各向异性和厚度上不同，使得它们各自的磁场建构性地干扰硬记录层中的一个或多个点，从而减少总SUL磁场响应 在硬记录层中的一个或多个点处的动态反转场大致为零，这减少了侧轨道擦除。

摘要： A magnetic recording medium, the order of layers in which is the substrate, the soft underlayer, the seedlayer, the 1st RuCrx-containing interlayer, the 2nd RuCrx-containing interlayer and the magnetic recording layer with preferably a oxides or nitrides-containing magnetic layer comprising grains, is disclosed. High-chromium ruthenium-chromium alloy used as inter layers significantly enhances coercivity and SMNR preferably due to the improved lattice match between RuCr inter layers and CoPt-based magnetic recording layers, and the surface energy of RuCr layers contributes to the performance improvement with the high-chromium addition into Ru inter layers.
